  1. Hi Stefan
    Few questions
    1) Is there version numbers of OOS? like OOS 2016 or OOS 2019 ?
    2) Do these versions of OOS work with all versions of Office documents 2016, 2010, etc?
    3) Where can I get succinct documentation of licensing requirements of OOS?
    Thanks

    1. Hi Ramen,

      1) no. There is only Office Online Server without a version as Office Online Server is an Evergreen product
      2) yes
      3) the following page has a link to a pdf file with licensing info on OOS:
      https://www.microsoft.com/en-us/licensing/product-licensing/office
      Check the “Licensing Microsoft Office software in Volume Licensing” link at the bottom.

      Cheers,
      Stefan

      1. Thanks Stefan

        Is OOS available as a Azure PaaS?

        How frequent an OOS farm needs upgrading to recent CUs?

        1. Hi Ramen,

          sorry – I do not know the answer about your Azure question.
          As for all products security fixes for OOS should be evaluated and applied as soon as possible.

          Cheers,
          Stefan
